Jessica Chastain rolls up her sleeves and gets tough as a DC lobbyist with hidden sympathies
Here is Jessica Chastain flexing her extraordinary Meryl Streep-like range and just about keeping this convoluted political thriller in the realm of enjoyably watchable. Her character is Elizabeth Sloane, a ruthless Washington, DC, lobbyist so fierce that when she smiles her wolfish smile – baring teeth through blood red lipstick – she looks as if she could devour a congressman in a single mouthful.
In the shadowy world of paid-for politics and special interests, Elizabeth is a power player, the go-to lobbyist for corrupt regimes and evil corporations. But when the gun lobby approaches her to sell weapons to female voters, Elizabeth switches sides, joining a do-gooding firm of cardigan-wearing charity workers. (Not so morally bankrupt after all.) Surprisingly, since she is a boss from hell accustomed to making 3am phone calls and publicly humiliating the team, her staff goes with her, mostly.
Chastain is a wonder. Her character could give Cersei Lannister in Game of Thrones lessons in cunning and wreaking vengeance. But we see her intelligence and, in the end, her human side. And she volleys the Aaron Sorkin-ish dialogue like Roger Federer in his prime. All of which helps you overlook some plot implausiblities and double-crosses.
